Abstract

An adaptive architecture for video effects allows a transformed image from a digital video effects (DVE) system (14) to be inserted at any desired point along a video path through a production switcher (12) while maintaining strict timing requirements between the digital video effects system and the production switcher. The transformed image from the DVE system is input to a primary input bus as well as to a fill video input of a downstream keyer (DSK) for the production switcher. A key signal from the DVE system is input to an effects key input and a key input of the DSK for the production switcher. The DVE system has a genlock timing system (26) that provides a variable output timing signal to synchronize the transformed image with the video of the production system at the desired point of insertion along the video path. The DVE system also has an output overlay mixer (24) that passes the program video from the production switcher to the system output unless the insertion point is at the output of the production switcher, at which point the transformed video is overlaid on the program output. The desired insertion point is determined by a topology mode indicator included within the keyframes that are programmed to produce a desired video effect.
